41 * glob(3) -- a superset of the one defined in POSIX 1003.2.
43 * The [!...] convention to negate a range is supported (SysV, Posix, ksh).
45 * Optional extra services, controlled by flags not defined by POSIX:
48 * Escaping convention: \ inhibits any special meaning the following
49 * character might have (except \ at end of string is retained).
51 * Set in gl_flags if pattern contained a globbing character.
53 * Same as GLOB_NOCHECK, but it will only append pattern if it did
54 * not contain any magic characters. [Used in csh style globbing]
56 * Use alternately specified directory access functions.
58 * expand ~user/foo to the /home/dir/of/user/foo
60 * expand {1,2}{a,b} to 1a 1b 2a 2b
62 * Number of matches in the current invocation of glob.
64 * sort alphabetically like csh (case doesn't matter) instead of in ASCII
